At the 1923 grouping they passed to the London and North Eastern Railway, who classified them E4. Eighteen survived into British Railways ownership in 1948, and the last was withdrawn in 1959, making them the last 2-4-0s at work in Britain. Their BR numbers were 62780–62797. OverviewDerived from the GER Class T19 but with much smaller {{convert|5|ft|8|in|m|3|adj=on|abbr=on}} driving wheels and intended for mixed traffic work, ninety T26s were built between 1891 and 1896 with {{convert|17|x|24|in|mm|0|adj=on|abbr=on}} cylinders (later {{convert|17.5|x|24|in|mm|0|disp=or|abbr=on}}) and {{convert|140|psi|kPa|0|adj=on|abbr=on}} boiler pressure, numbered 417–506. From 1898 some locos were rebuilt with {{convert|160|psi|kPa|0|adj=on|abbr=on}} pressure boilers thus when an additional ten T26s (numbers 1250–1259) were built in 1902 these were fitted with the new boilers as standard.[1] OperationThe GER used air brakes but, when introduced, more than half the T26 locomotives were additionally fitted with vacuum brake ejectors for operating over the lines of other railway companies. T26s were particularly associated with the movement of horses by rail to and from Newmarket Racecourse, and thus travelled widely.[1] T26s were often used on passenger trains to the Norfolk Coast, particularly Wells and Cromer. After the grouping of 1923 Claud Hamilton 4-4-0s took over most passenger traffic to Wells.[2] Accidents and incidents
LiveryOn introduction the T26 locomotives were painted in the standard GER livery of Ultramarine Blue over an undercoat of French Grey, with black smokebox and vermillion buffer beams and lining. From 1915 locos were not given a top coat and ran in French Grey undercoat but with the boiler bands picked out in black.[5] After the amalgamation of the GER into the LNER in 1923 (the Grouping), the E4s received the LNER mixed traffic livery of black with single red lining and red buffer beams. This lasted until the early 1940s when unlined black with red buffer beams was introduced, and the surviving locos were to carry this livery until their withdrawal. PreservationOne (GER No. 490, BR No. 62785) has survived to form a part of the National Collection and is currently located at Bressingham Steam Museum. There are Transacord recordings of their gentle chuffing through the byways of East Anglia.
